That weekly grind?
Let an app handle it instead.
Tell us about that one task you've been duct-taping with spreadsheets, chat, and forms.
A day later, you get back a URL for an app that handles it.
Spend the time you save on real work. An MVP that costs millions of KRW from an agency — yours in hours, free.

Time you'll get back
All those weekly hours? Spend them on what matters.
Real time saved by real apps shipped on fingr. Same shape every time: simple, repetitive, work you shouldn't be doing yourself.

Convert these hours to billable rates or to focus regained on real work — either way, the value is real.
Pick the one task you repeat every week. An app can take it over before this week is out.
Start with what you're already paying
That tool you pay hundreds a month for —
it doesn't even fit you.
If you're paying for unused features, hacking around mismatches, and bending to someone else's design — build a version that actually fits you. If others share the pain, you can sell it.
Pay only for what you use
Are you using just two or three features of that ₩300K/mo tool? Build an app that does only those. Watch fixed costs drop overnight.
Your workflow, exactly as it is
Tired of exporting spreadsheets just to re-import them so they fit someone else's design? An app that follows your flow has no detours. The fields you want, the buttons you want, the alerts you want.
You're not the only one with this pain
Once you've built it for yourself, sell it to others with the same problem. Add a domain and billing — now it's a product. Small niches can become small (or steady) income.
The SaaS era defaulted to "use what someone else built." Now you can default to "build what solves your problem." fingr ships the first version within a day, for free.
Yes, really fast
Three weeks of agency work — by end of day.
Skip the complexity — your only job is describing one problem.

Same idea, compared by initial-version cost & time
※ First-version builds are free during beta.
Maintenance plans for revisions, hosting, and ongoing support will be published when the beta ends — priced reasonably against agency maintenance.
Example · Rainbo (pet funeral home ops)
Booking, billing, and CRM bundled into a domain-specific SaaS. Agency quote was around ₩8M / 3 weeks; fingr beta delivered a same-day initial version, free — letting them validate viability before committing.
